BiLiLuBat - Bimodal Li Air Battery [Original in Deutsch: Entwicklung von bimodaler Hochenergie- Lithium-Luft Batterie]

Due to decreasing raw oil reserves and increasing pollutant emissions caused by passenger and freight traffic, the further development of electric gears is essential. Especially the driving range is an important issue to make electro-mobility more attractive to future operators. The maximum energy density of current lithium-ion batteries is limited by their chemical material composition, and thus such batteries are not satisfactory for the practical application of electric vehicles (EV). Li-air batteries (LAB) have attracted much attention as a possible alternative, offering the highest theoretical energy density (3500 Wh/kg) compared with other current battery systems, rivaling that of gasoline (13,000 Wh/kg). But several challenges have to be overcome until a high energy, reliable LAB can be achieved. Therefore, the aim of the project is to resolve these difficulties and evolve a bimodal li-air battery with optimized cell components, which is applicable to future electric vehicles. Bringing together the competence and the experience of all project partners, the present proposal has the potential and the infrastructure for developing of new generation of electrical energy storage system. To achieve this goal, three main targets has been set: optimized design of the li-air cathode, development of suitable bifunctional catalyst and optimization of the electrolyte system. Already at an early stage of development highly efficient simulation software will be used on the basis of experimental data by the company partner AVL List GmbH to support the partners in the areas device safety, cell management and battery design. The expert knowledge in the field of Sustainability will be available to the consortium through the company partner PE CEE Nachhaltigkeitsberatung & Software Vertriebs GmbH for the estimation of environmental relevance of the materials and eco-design of the developed Li-air battery with investigation of the possible recycling potentials.
